PLOW.

SPECIFICATION forming part of Letters Patent NO. 784,279, dated March 7,1905.

Application filed August 5, 1903. Serial No. 168,349.

To (LM zul/tom, t may cm2/cern,.-

Be it known that l, PETER W. REIFSNEIDER, a citizen of the UnitedStates, residing in Limerick township, in the county of Montgomery andState of Pennsylvania, have invented certain new and useful Improvementsin Plows, of which the following is a specification.

My invention relates to improvements in plows; and it has for its objectto render the point readily detachable and adjustable.; and it consistsof the combination and arrangement of parts, including theirconstruction, substantially as hereinafter more fully disclosed, andspecifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure 1 is a perspective view of the same. Fig. l is aninverted or bottom view thereof. Fig. 1b is a transverse section takenon the line rc of Fig. 1. Fig. 2 is a detail perspective view of themoldboard -wing and the share. Fig. 3 is a similar view of the lappingor splicing plate effecting' connection be tween the share` moldboard,and moldboardwing. Fig. 4 is a detail perspective View of the moldboard,disclosing more especially the forward lateral edge notch therein toaccommodate the converging edge of the share, whose forward edge engagesone of two lateral grooves in the plow-point adjacently to said notch.Fig. 5 is a forward end or front elevation of the moldboard. Fig. 6 is adetached perspective view of the chisel-pointed bar forming theplow-point.

In the carrying out of my invention I provide a moldboard 1, havingintegral or cast therewith upon its under side a socket or housing' 5,laterally forming in part the landside, said moldboard having a separatewing or extension 1a dished upon its outer or front surface rearward andsuitably connected or coupled to said moldboard, the connection, asindicated in dotted lines at 1b in Fig. 1, being effected upon the underside of said mold board and wing or extension. A preferablychisel-pointed bar 4 has lateral longitudinal grooves 1], into one ofwhich extends a lug 14 u )on the inner surface of the housinO` 5 andwhich bar is inserted through the aperture 3 of said housing' 5. Thepointed or tapered end of said bar 4 projects a suitable distance beyondthe forward end of the mold board to form or constitute the plow-point,as at 13, while the opposite end of said bar extends some distancerearward from said moldboard and is suitably held in such position by abracket 6, as seen in Fig. l", integral or cast with the moldboard. Saidbracket, like the part 5, takes under or receives said plow-point bar4andhas lugs or projections 14 engaging the grooves 11 of said bar-as,for instance, in the initial use of said bar and when reversed after'the wearing of the point for further use in reversed position-saidbracket also having an arm 7 arranged higher, having an aperturereceiving a bolt 9, suitably secured therein by a nut and insertedthrough an aperture in the moldboard l, to which it is held by headingthe same for bracingsaid bracket.

A share 16, deiieeted or standing outward and downward at the requiredangle from the plow-point bar and moldboard, has its forward end 17 and18 accordingly adapted to engage said bar at the forward end of one ofthe grooves 11 of said bar, it being notched in approximately V-shapedform, as at 3, and a narrow margin 3X left beyond the notch 3u. Saidforward end of share is also stepped at that end, as seen 'in Fig. 2, toengage laterally the socket 5, while the upper surface of said share hasa longitudinal shoulder or upraised portion 16, adapted to engage orabut the lower edges of said moldboard and its wing 1as seen in Fig. 1,to prevent inward lateral displacement of said share, the outer surfaceof said shoulder itself sloping in continuation of the correspondingsurface or declination of said moldboard and wing. The forward lateraledge of the socket or housing 5 is obliquely notched in angular V-shapedform, as at 3b, as shown in Fig. 4, in correspondence with theoutstanding angular disposition of the share 16 to conform to and eectthe requisite fitting together of said parts at that point.

Overlying or covering the joint or meeting' edges 0f the moldboard-wing1u and the share lstaples 19D, projecting from said thickened portion19a through apertures or holes 19c in said plate 19, and keys or wedges191 inserted through the projecting portions of said staples. The outersurface of the thickened portion or enlargement 193L of themoldboard-wing 1fL is inclined, as seen in Figs. 1b and 2, with said fsurface arranged flush with the corresponding surface of the share 16,thus providing for securing a clamping action of the lower longitudinaledge of the binding or clamping plate 19 upon said share, therebyefecting the retention of the latter firmly in position. Said thickenedportion or enlargement 19 is reduced a suitable distance from the bottomlongitudinal edge of the moldboard-wing, as at 19e, said reductionextending from a rear edge inclined shoulder 19f on the moldboard,forming a stop for the corresponding edge of a flange 16" of the share16 and over which share and shoulder lies the clamping-bar 19, securedin place as above described.

To adjust the angle of the chisel-pointed bar forming the plow-point L1,it is only required to properly manipulate the nut of the bolt 9.

It will be understood that latitude is allowed Vherein as to details, asthey may be changed and a bracket integral with said moldboard andhaving a lug engaging either of said grooves, said bracket being bracedin position from said moldboard.

2. A plow having a moldboard, with its wing, a share applied to saidmoldboard, said wing' having an inclined underneath thickened portionprovided with a longitudinal recess, said wing having staples projectingtherefrom, and a clamping-plate engaging said inclined thickened portionand having apertures receiving said staples and keys inserted into saidstaples, outside of said plate.

3. A plow embracing a moldboard with its wing, said wing having aninclined underneath thickened portion provided with a longitudinalrecess, said moldboard having a housing upon the under side, at theforward end,'a plow-point bar carried at its forward end by said housingand having lateral longitudinal grooves, a rear end-supporting bracketfor said plow-point bar, having a lateral lug en gaging either of thegrooves of said bar, a share having upon its upper surface alongitudinal shoulder engaging the bottom edges of said moldboard andwing', said share also having a stepped and notched oblique lateral edgeopposed to said plow-point bar and moldboard, said housing also having alateral angular notch at its forward edge receiving the correspondingedge of said share,'and a clamping-plate secured to, and resting upon,the underneathinclined surface of said moldboard-wing and bearing uponsaid share, said share having its rear end portion let into the recessof said wing. i

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
